Be a known that I, Tnoms-SHAw, of the city and county of Philadelphia, Pennsylvania, have invented ai new and'improved Pump; and I hereby-declare the following to be a full, clear,*and exact description of "the same,- reference being had to the accompanying drawing and to the letters of reference marked thereon.

My-iuventiQneonsiSts in the employment of a number of propeller wheels, eaeh alternate one stationary, and the others revolving, and of reversed angle in a 'tu he in the manner and for the I purpose as hereafter described. 7

The object'of the invention is to pump sand-and water-to any height by a constant application of howerto the ascendingcolumn, as hereafter described.

In order to enable otherstouse and practice my invention, '1 will proceed to describe its construction and On relerence tothe. accompanying drawings, which form part of the-.specifitilil ln; j l: gitudin section-through the center of pump, oi 'hi'choj-is metal tube sur-f rounding theubnfi'tsefit nslof tn ferfthe purpose of keeping themlifhgethj and The propelleriirlieels' ,secuifd' v'olvingfshaft d, and similar whjeels,,1i,' ithZ-blade's of reversed angle,

" I etubaare secured stationa IL r The shaft d revolircsuu ourn-l in center of disk f on its lower end," and'has asimilarjournal in the ce'u-' ter of disk i on its ,upper-fe'mi,and is provided with a pulley, It, all for the. purpose as hereafter described.

. The apertures g arefoi' tbeentiance of sand or fluid, and the chamber eahd pipe ltjare for the exit of the The pump isop e rated iii-this wise: it is suspended vertically, orat an angle into the material to be pumped,

or, if circumstancesrequire it, it may operated in a horizontal position.

Power is applied to revolve 'shaftd by a cord, or any of the ordinary methods, in a direction indicated by angle of propeller-wheel, therotation of which forces. the fluid in direction longitudinal with the tube and" with the curve of revolution, All the force ni'oringin' the curve of revolution is'th'rown violentlyagainst the wings of stationary-wheel, which eausesthe tnarerial to glanceofl' and move in a'line parallel iv'ith the tube,

when the blades of the next revolvingwheelcatch upon the fluid or material and move itinthe same manner upon the next succeeding stationary wheel, and so on I alteinately,.until the column of. 'urateror other ma- .tei'ial-is lifted to thedesired'height It will he observed that this constant lifting at every part of-r-the' column handles thematerialas if it was .a 'rope' of sand, and willlift water, 'mud, and sand to 'janyi desired heighqwithout reference to, or aid from f -,'el tm ospheric pressure; audthat it canhe used fol-dredging in -otherpurposes,aud that the inlet and outlet apertures of tube, a can behiodifiedyvit-hout any alteration-in the; result, and; that the outer tube a can be dispensed v it'hl-by providing flanges on each end of tubes b, that they may-heholted'together in the same manner asordinary flangepipe;

"The alternate stationary and revolving propellerwheels, arranged in a tube with blades of reversed anglespiutheinauner and for the purpose set forth.
